Positron emission tomography is a nuclear medicine imaging technique which produces a three-dimensional image or map of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide , which is introduced into the body on a biologically active molecule. Images of tracer concentration in 3-dimensional space within the body are then reconstructed by computer analysis. In modern scanners, this reconstruction is often...

I enjoyed my time with this company. It's kind of rude to blame the billing department when some of the office managers can't alphabetize. If I ever had an issue the billing department solved it and if I made a mistake they let me know about it. I enjoyed my work, but I heard alot of others complaining and never figured out what about. If you don't work at something it withers. Failure is a team effort. If you don't think you're victims of this economy, you're fooling yourself. It is unfortnuate how it happened, but I am grateful for the time I had there and the friends I made.
